You can also use the resxtop or esxtop command-line utilities. The utilities provide a detailed look at how ESXi uses resources in real time. For more information, see the vSphere Resource Management documentation.

Check with your storage representative if your storage system supports Storage API - Array Integration hardware acceleration features. If it does, refer to your vendor documentation for information on how to enable hardware acceleration support on the storage system side. For more information, see Storage Hardware Acceleration.

When you use EMC CLARiiON or Invista arrays for storage, it is required that the hosts register with the arrays. ESXi performs automatic host registration by sending the host's name and IP address to the array. If you prefer to perform manual registration using storage management software, disable the ESXi auto-registration feature.
